Abstract: PURPOSE:To obtain a high-quality record picture, by sufficiently feeding a magnetic fluid into a recording needle, and uniformly absorbing and recovering an excess amount of the magnetic fluid near the top end of the recording needle so as to form a uniform stabilized projection. CONSTITUTION:A magnetic fluid 4 in a tank 8 is fed onto a projecting magnet 3 by a feeding means 5 in a manner such that the amount of the magnetic fluid 4 retained by the top end of a recording needle 1 will be excessive. When air is inhaled through an inhaling hole 15 by the pump 17 of a recovering means 13, the magnetic fluid 4 retained by the top end of the recording needle 1 is hardly separated, but the excess amount of the magnetic fluid 4 near the top end is let flow toward the inhaling hole 15 since a magnetic field near the top end of the needle 1 is weak. The excess amouunt of the magnetic fluid 4 is recovered in the tank 8. In this way, a projection 12 having a uniform proper step  A is formed. When voltage is charged between the recording needle 1 and a controlling electrode 9 by a controlling circuit 11, Coulomb's force is applied to the top end of the projection 12. Consequently, the magnetic fluid flies toward a recording body 10, and a recording picture is formed on the recording body 10.
